Bipap Pressure Suggestions

Bipap Pressure Suggestions
I am still relatively new to Bipap. I posted some charts from the past couple days playing around with the pressure settings. I was prescribed IPAP of 9 and pressure support of 4 after and overnight sleep study. However, I didnt feel the best with that so I have been steadily adjusting my pressures.

Is there a negative to increasing the pressure support? Any suggestions on if I should bump/reduce the PS or IPAP based on these charts?

Any advice is welcomed!

RE: Bipap Pressure Suggestions
Your best results appear to be at PS 4.0 and those results seem to deteriorate with higher PS. I think it would help if you would open up Vauto mode by adding about 3-cm to the EPAP min plus PS and make that the max pressure. As it is, you are using fixed pressure VPAP. Events are low in all of these charts, so EPAP min does not seem to be affecting the obstructive apnea rate, and there does not seem to be a central apnea or hypopnea problem with PS between 4.0 and 4.6, although CA event rates rise with higher PS. Based on what I'm seeing here the obstructive events are minimized with EPAP min 6.0, and CA is minimized at PS 4.0. I would just set a IPAP max of 12.0 and let it ride for a couple nights..

supyasieve,

Unless you feel like a bad night, I would suggest a couple of nights at a setting. Sometimes there are small differences night from night even at the same settings.

Alright. I will try this for a few days and post results. Thanks for the reply!

Here are my results over the past 3 nights. Note, last night I tried a F&P evora vs the normal f20. 

Let me know what you think. Still tired most days, but dont feel as much of the headaches and such as before.

RE: Bipap Pressure Suggestions
Pressure is very steady and events have disappeared. If you want to try fixed pressure to eliminate the possibility that pressure changes are disruptive to sleep, just keep EPAP min 6.0, IPAP max 10.0 and PS 4.0. This looks like excellent therapy and may just take some time to settle in. The big spikes in flow rate and minute vent all correspond to brief mask leaks, so they are not necessarily arousals, but the occasional leak spikes might be movement.

Sleeprider,

I never noticed you had posted while I was posting.

Of course I always defer to you.
